5. Use the graph of f given below to nd all values of x = a where the function is discontinuous. For each point of discontinuity, give the following: (a) 1in f (x) I)' (b) mqx) I3 (C) limeC) ID (d) f (a) The graph is discontinuous at x = The graph is discontinuous at x = (a) HIT! f (I) (a) limx) X) 1}4 0)) En} f(x) 0)) lirqx) X4?\" xaa (c) limf(x) (c) ligx) XN (d) f (a) = (d) f (a) =
